MicrosoftWindows Server 2008 R2 Hyper-V builds on the architecture andfunctions of Windows Server 2008 Hyper-V by adding multiple new features thatenhance product flexibility. The adoption of virtualization in the enterprise hasincreased flexibility in deployment and life cycle management of applications. ITprofessionals deploy and use virtualization to consolidate workloads and reduce serversprawl. Additionally, they deploy virtualization with clustering technologies to providea robust IT infrastructure withhigh availability and quick disaster recovery. Even so,customers are looking for more flexibility.

This research was madenot only to study and show possibilities of

next generationvirtualization,

but also to estimate how their development and deployment

will go on infuture and what it will cost forend users.

Aspects of this research include:

•

Main characteristics:

•

Performance

•

Fail

safety

•

Energy consumption

•

Cost

•

Available devices

In this research I’m going to discuss mainHyper-V

features likefailsafety

anddata transfer speed.

2. Literature Review

During the research process the following literature sources were used:



http://en.wikipedia.org/wiki/Hyper-V

Here you can find general information about technology, overview,development history, features and current state of technology.



http://www.microsoft.com

There isweb sitethat

dedicated toMicrosoft products

and technologies.All the news about new developments and technologies, projections andestimates can be found here.



http://support.microsoft.com

Community interested inMicrosoft

technologies.Official representativesof Microsoft and other users share their experiences using the products andsolve problems.

General information about technology was taken from different articles on the webresources like Wikipedia. Current information about usage of this technology can be seen instatistics from around the world.

To verify the critical factors for technology assessment, we used a practical approach andexperience gained from other studies. Of the major competitors of this technology can bedistinguished VMware. This company has made a good place for the virtualization market.

4.Results andDiscussion

Last years usage ofvirtualization technology

is

growing

rapidly. For largercompanies this is a good way to save money on hardware, facilities and tariffs forelectricity.

New in Windows Server 2008 R2 with SP1, Dynamic Memory enables customers tobetter utilize the memory resources of Hyper-V hosts by balancing how memory isdistributed between running virtual machines. Memory can be dynamically reallocatedbetween different virtual machines in response to the changing workloads of thesemachines. Dynamic Memory thus enables more efficient use of memory whilemaintaining consistent workload performance and scalability. Implementing DynamicMemory means that higher levels of server consolidation can be achieved with minimalimpact on performance. Dynamic Memory also means larger numbers of virtualdesktops per Hyper-Vhost.

One important difference from rivals Microsoft technology-

the ability to remotelymonitor a cluster of the center console-

Server Management Suite Enterprise.

Low-cost product as a plus among the competitors. Asupply of technology, completewith powerful operating system, thereby avoiding the complex third-party applications,is crucial for many companies.

Most respondents were aware of virtualization technologies and more than half use it.However, approximately 20% of respondents had never heard of such technologies.Perhaps this is due to a lack of interest among server operating systems.

Conclusion

Now we can summarize most of the new technology advantages, including:

•

Low cost

•

Convenientcontrol

•

Excellent fault tolerance

•

Two

times increased efficiency over current systems

•

Better user experience

Thus we have the technology available even to small companies, which allows you toreduce costs, increase productivity and Failover Clustering Data.
